How Do Fiber Optic Couplers Work?

Fiber optic couplers either split optical signals into multiple paths or combine multiple signals on one path. Optical signals are more complex than electrical signals, making optical couplers trickier to design than their electrical counterparts. Like electrical currents, a flow of signal carriers, in this case photons, comprise the optical signal. However, an optical signal does not flow through the receiver to the ground. Rather, at the receiver, a detector absorbs the signal flow. Multiple receivers, connected in a series, would receive no signal past the first receiver which would absorb the entire signal. Thus, multiple parallel optical output ports must divide the signal between the ports, reducing its magnitude. The number of input and output ports, expressed as an N x M configuration, characterizes a coupler. The letter N represents the number of input fibers, and M represents the number of output fibers. Fused couplers can be made in any configuration, but they commonly use multiples of two (2 x 2, 4 x 4, 8 x 8, etc.).

The need for fiber optic couplers

We use electronic couplers all the time: such as a telephone coupler which lets you connect both a telephone and a fax machine to the same telephone line. Or a CATV coupler which lets you connect several TV sets to a single cable from Comcast. Basically you can buy these couplers from Home Depot or other electronic retailers.

Optical couplers have the same functionality as electronic couplers: They split the signal to multiple points(devices). Fiber optic couplers are needed for tapping(monitoring the signal quality) or more complex telecommunication systems which require more than simple point-to-point connections, such as ring architectures, bus architectures and star architectures.

Passive couplers and active couplers

Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.

The difference between electronic couplers and fiber optic couplers

Electronic couplers are easy to make because electric current flows as long as you have physical contact between conductors. But optical signal is in a completely different domain. You have to align the tiny optical fiber cores precisely (9um for single mode and 50um or 62.5um for multimode fibers), so there won't be a huge power loss when you split the signal.

The Principle Of The Optical Switch And Types

The optical switch performance parameters are many, such as: the fast switching speed, high isolation, low insertion loss, polarization insensitive and reliability, the different areas of its requirements also vary. Protection switching system used in traditional optical mechanical switch its kind, the past few years the rapid development of a new type of optical switch, such as: thermo-optical switch, the LCD switch, optical switch, sound and light switch, MOEMS optical switch (MOEMS, micro optic electro mechanical systems), bubble switch or the like. In the field of ultra-high-speed optical communication Mach - Zehnder (Maeh-Zehnder) interferometer type the optical switch, nonlinear loop mirror (NOLM nonlinear optical fiber loop mirror) light switch and light control switch.

1.Mechanical optical switch

Traditional mechanical optical switch works: by the power of heat, electrostatic, rotary micro-mirror, the light sent directly to or reflected to the output. Characterized by relatively slow switching speed, good price, market prospects in many areas, but bulky and not easy to scale integration shortcomings limit its application in future optical communication field. On this basis, in recent years, developed rapidly MOEMS optical switch, it is the combination of a new switch of the micro-electromechanical systems and conventional optical technology, particularly those having the data format of the optical signal and transparent, with the polarization-independent, differential loss is small,good reliability, speed, easy integrated advantage.

2.Electro-optic effect switch

Optical switch of the electro-optical effect and more by photoelectric crystalline material (such as LiNbO3 or other semiconductor material) waveguide material, two waveguide connected MZ interferometer structure, the applied voltage can change the refractive index of the waveguide material, to thereby control the phase difference of the arms,interference effects of the optical off. It is characterized by fast polarization and higher costs. For the 3dB coupler, the two lightwave equation satisfy the mode coupling, so that the propagation constants of the two optical waveguides are equal, B0 = 0, at the output terminal of the the 3dB coupler 2 is obtained:

|A3|2=|A0|2sin2(Ф/2)

|B32=|A0|2cos2(Ф/2)

In the equation A0, B0 - input light wave amplitude; A3, B3 - output light wave amplitude; Ф - Lightwave phase.

3.Light control switch

Now more mature models: the production of all-optical switch based on the the NOLM principle and SOA nonlinear effects (such as XPM: cross phase modulation). They are not only used for ultra-fast switching exchange, but also for all-optical signal regeneration and ultrafast wavelength conversion is a promising all-optical switching technology.
SOA respectively disposed in the two arms of the MZ interferometer, the switch control pulse injection arm, pulse changes will cause the change in refractive index of the SOA, causing arms retardation change △ Ф, that is: △Ф=-(2π/l)(dn/dN)(τe/[1+(wτe)2]1/2L×Vg×g×△S×cos(wτ-q)

Wherein, L - the signal wavelength; dn/dN- refractive index set the amount of change of the carrier density; L-SOA cavity length; the τe-carrier lifetime; VG-group velocity; g-gain coefficient; △ the S-the amplitude of the carrier density changes; the phase delay between the change and the modulation signal of the Q-carrier density.

What Is a Network Adapter?

In order for a computer to connect a network, a component known as a network interface card is required to provide the physical connection to the local network media. Computer normally have some form of expansion card containing the network interface controllers that are plugged into one of a number of different types of Computer Bus. Most desktop computers to date had a network card that fitted into a PCI slot. PCI stands for Peripheral Component Interconnect and was originally developed my Intel, but is now a standard used by almost all manufacturers that produce peripheral devices for connectivity with a computer.

As Ethernet has been the dominant Data Link Layer standard for Local Area Networks for some time, Ethernet Network Interface Cards have been produced in their millions to allow computers the connectivity through hubs, optical switches and routers with other computers. These network cards cost as little as a few pounds or dollars and allow computers to communicate across an internetwork and be identified by means of a unique physical address known as a MAC Address.

Most people refer to such a network device as a network interface card, Ethernet Card or Fiber Optic Network Adapter and they will have an RJ45 female connector, into which a male connector on an Ethernet Patch Cable is connected.

Any Network Adapter will require drivers, which are applications used by the computers to communicate with, and control the actions of the Adapter. Most modern computers will automatically detect a new device and apply the correct drivers, or prompt for the location of the drivers which may be on a disk supplied with the card in the case of a PCI Network Card.

Although a lot of modern computers actually have the NIC built into the motherboard, there is still a need for network cards that plug into a computer as there are so many computers still functioning on networks that do not have motherboards with that capability.

At present, there are many manufactures and it's difficult to recommend one, the easiest way to purchase a cheap network card or fiber optic network adapter is certainly over the Internet from a specialist online retailer.

Tunable XFP Optical Module Will Replace The 300-pin Module

As operators deploy 100-Gbps backbone network in order to support the emerging high-bandwidth services and commitment, the future will be more and more turning to the WDM transmission architecture. It is estimated that by 2014, the the WDM module market value will reach $ 870 million. Tunable XFP optical module can be used to replace the existing fixed wavelength DWDM XFP modules, the market potential.

Not only that, the expert analysis, the product will also replace the existing high-performance 300-pin modules. Tunable XFP module can provide higher port density, power consumption than the 300-pin optical module greatly reduced, and thus most likely to win a large number of orders from the hands of the equipment manufacturers.

Tunable pluggable optical transceiver especially XFPs, has entered a practical stage. JDSU is the first to launch such products company, to achieve mass production in September last year. The cooperation of the company with 26 customers in the use of adjustable XFPs 12 customers and supplier.

At the same time, JDSU is committed to the adjustable the XFPs product power, in order to achieve the 300-pin modules for metropolitan applications. The way to achieve this goal is to deploy linear tunable XFP+ modules, with support of up to 200km transmission with EDC device. JDSU with the EDC vendors ClariPhy collaboration, with the demonstration on the latter still OFC2010 meeting the CL1012 EDC chip with the JDSU tunable XFP module. JDSU plan to begin shipping in the second quarter of this year linear adjustable XFPs, the company hopes to cooperate equipment suppliers and the EDC.

JDSU also said, the adjustable the XFPs market to make technology investments to become valuable, and look forward to the end of the year adjustable XFPs product shipments will exceed 300-pin modules, tunable 300-pin module shipments will grow this year.

With the continuous growth of the tunable XFP product demand, other companies have also entered the field. In the recently held OFC, Finisar exhibited 10G tunable XFP module.

Although more focus toward the WSS and 40G technology, Olcaro also plan to enter XFP field, in addition to Emcore also determined to join the field. The Emcore latest launch micro-ITLA (integrated tunable laser assembly), as the core of the tunable XFP products section.

Meanwhile, Menara Networks, Inc. announced the launch integrated OTN XFP products. The module G.709 framer, OAM and former integrated forward error correction in a XFP module light switch / router vendors as the main target customers. Juniper also introduced the corresponding products.

When Do You Use OTDRs?

We have brought in various OTDR manufacturers to teach their use to our students. Since most of our attendees are contractors, we try to give them a realistic overview of what jobs they will see and what tools they will need. It is very important to understand when you need an OTDR and when it is not appropriate.

If you are installing an outside plant network such as a long distance network or a long campus LAN with splices between cables, you will want an OTDR to check if the fibers and splices are good. The OTDR can see the splice after it is made and confirm it's performance. It can also find stress problems in the cables caused by improper handling during installation. If you are doing restoration after a cable cut, the OTDR will help find the location of cut and help confirm the quality of temporary and permanent splices to restore operation. On singlemode fibers where connector reflections are a concern, the OTDR will pinpoint bad connectors easily.

OTDRs should not be used to measure cable plant loss. That is the job of the source and power meter, which duplicates the actual fiber optic link, as we described in the first part of this article and is documented by every standard ever written for cable plant loss. The loss measured will not correlate between the two methods; the OTDR cannot show the actual cable plant loss that the system will see.

The limited distance resolution of the OTDR makes it very hard to use in a LAN or building environment, where cables are usually only a few hundred feet long. The OTDR has a great deal of difficulty resolving features in the short cables of a LAN and is more often than not simply confusing to the user.

And one OTDR manufacturer once told one of our Fiber U classes that they could justify the cost of an OTDR simply by using it to test the length of the fiber on a reel when they get it to make sure they got what they paid for. The class laughed at the instructor and pointed out the cable manufacturers mark length on the cable jacket and a $2 calculator would do as well!

Since OTDRs are very expensive and have only specific uses, the decision to buy one must be made carefully. For that reason, most instrument rental companies will rent one for a few days or weeks when you need them. However, if you are not familiar with their operation or cannot understand the results of OTDR tests, it would be much better to hire a specialist to do the testing for you.

XFP Module VS SFP Module

Technical stuff really gives us a hard time understanding what they are. Though most of us are not technician, we still want to understand the latest trends of our time. Even in the line of telecommunications it has developed progressively. There are a lot of transceivers being produced to increase your signal. A transceiver is a package with a transmitter and a receiver. To be able to transmit data, we need transceivers. The most common way of transmitting data is to use light-based fiber optics. The use of electronic signals is the traditional and slower way of transmitting data. The best modules to use today are the XFP and SFP modules.

XFP module

XFP module also called XFP transceiver and what is an XFP module? "XFP" stands for "10 Gigabit Small Form Factor Pluggable." With XFP you will surely experience a fast transmission of data in your computer network including your telecommunication links.

According to Wikipedia, XFP is a hot-swappable and protocol independent module. It means that you can replace the component without shutting down the whole system. XFP can replaced without interrupting the operation of your system. Its usual operation is at optical wavelengths of 850nm, 1310nm, or 1550nm. To be able to install this module in your computer, you should have one of these: 10 Gigabit Ethernet, 10 Gbit/s Fibre Channel, Synchronous Optical Networking at OC-192 rates, Synchronous Optical Networking STM-64, 10 Gbit/s Optical Transport Network OTU-2, and parallel optics links. XFP modules are able to function with just a single wavelength or dense wavelength division multiplexing techniques.

SFP module

“SFP” stands for “Small Form-factor Pluggable.” It is a compact, hot-pluggable transceiver used for both telecommunication and data communication applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic orcopper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsoletes the formerly ubiquitous Gigabit interface converter (GBIC); the SFP is sometimes, erroneously, referred to as a ‘Mini-GBIC’ (although no such device has ever been defined in the MSAs).

The Development of Fiber In The Telecommunications Environment

An important principle in physics, the theoretical basics of the optical fiber communication: in the glass medium can carry more information over longer distances than electrical or radio frequency signal can be copper, Our fiber optic splice closure is high quality and competitive in price coaxial cable or wireless medium.

The scientists first challenge is the development of glass, the pure light of one percent will be retained in the one kilometer distance from the end of the existing copper-based telephone system without replay transmission. Attenuation, this light to retain one percent conversion of 20db per kilometer (dB/km) glass material.

The researchers of the glass all over the world in the 1960s, the challenge, but in 1970 a breakthrough, Corning scientist Dr.Donald Keck, Robert Maurer and Peter Schultz created less than 20 dB per kilometer attenuation fiber. This is the most pure glass.Our mission is to save shoppers time,
money by bringing together everything that's needed to buy a fiber splitter.

The work of three scientists, lead to the commercialization of optical fiber technology to confirm. Since then, the technology has been much earlier, in terms of performance, quality, consistency and applications.

Closely with our customers has made it possible for scientists to understand what need to be modified by a corresponding increase in product design and manufacturing and to develop industry standards for fiber.

The commitment of the optical fiber technology has spanned more than 30 years, and continue efforts today to determine how fiber is currently used and how it can meet the challenges of future applications. As research and development work to improve the fiber glass purity has reached high levels. Today, the optical properties of the fiber close to the theoretical limit of silicon-based glass material. Purity, improved electronic systems combine to make the figure of the optical fiber transmission of optical signals of hundreds of kilometers there is no amplification. Early 20 db per kilometer attenuation level achieved compared to 1550 nm and 0.25 dB per kilometer, less than 0.35 dB per kilometer at 1310 nanometers (nm), to testify to the incredible improvement drive.

How To Wire a Wall Network Port

You may know how to make your own network cable, let's talk about how to hide it. Depending on your home, the actual job of running patch cables behind the wall or under the house, and making both of its ends come out of the wall, can be ticky. You might want to hire a handyman for that job, especially the part where you need to cut holes in the wall. In this tutorial, i just teaching you how you can make an ethernet jack, with the ends of the patch cable already sticking out of the wall. And this is a CAT5e Network Cable, also known as a RJ-54 Ethernet jack. A CAT6 jack has the same wiring, however.

Before you do these what tool do you need:

Puch down tool, a puch down tool just cost your several dollars, and Ethernet jack and wall plate. You can buy these separately and you can find a wall pate that can house more than one jack.

The Steps:

a. Using the Fiber Cable Stripper to strip the patch cable about 2 inches from its end. You can strip more than 2 inches if needed, since the extra length will be cut off, but note that there's a limited amount of patch cable coming out of the wall so you don't want to cut it too short. Spread the eight wires from one another. There's no need to put them in a particular order since the pins on the Ethernet jack are color coded.

b. Placing the cable in the middle of the jack and push its wires on the pins of the matching color for the 568B standard. This means that the orange wire goes into the orange pin, the blue wire goes into the blue pin, and so on. Technically, you can use the 568A wiring standard, but in this case you'd need to do the same with the other end. generaly, you want to avoid using 568A for network ports because it could cause problems in the future if somebody else repairs the port and uses the more common 568B standard.

c. Using the punch down tool to punch these wires down on their pin in one quick motion. If you do it right, the wire will be punched down, and the excessive wires will be cut off.

Now you just need to install the wall plate and you are done with one network port. You can make another port at a different end of the house that connects to the port you have just made if you want to have just a single wired connection.

Brief Introduction of Fiber Optical Auttenuator

Fiber Optical Attenuator is used an electronic device often reduce the level of performance of an optical signal in a fiber optic communication system. In the optical fiber is also known as transmission loss attenuation. Attenuation is an important element in order to limit the transmission of a digital signal, at large distances. An optical attenuator reduces this optical signal as it propagates along a free space or an optical fiber.

There are three basic types of fiber optical attenuator, fixed attenuators reduce light signals through certain amount with negligible or no reflection. Because signal reflection is not an issue, fixed attenuators for precise data transmission becomes known. Above a certain temperature, size and height Fixed attenuators are often used in order to improve inter-stage matching circuit in an electronic circuit. Thorlab fixed attenuators are dB from 5 dB to 25. Mini-Circuits’ fixed attenuators are packaged in robust plug-in and plug models. They are available in both 50 – and 76-ohm models spanning from 1to 40 dB DC to 1500 MHz.

Optical variable attenuator is a double window (1310/1550nm) of passive components. The variable optical attenuator could continually and variably attenuate the light intensity in the optical fiber transmission. Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link.

In the variable optical attenuator, resistors, which replaced with electronic devices, such as the metal-semiconductor field-effect transistor and PIN diodes. Variable Optical Attenuator light signal or beam in a controlled manner, thereby producing an output optical beam with different attenuated intensity. The attenuator is the power ratio between the light beam from the device and the light beam in the device for a variable rate. Variable optical attenuators are typically used in fiber optic communication systems to regulate optical power to damage in optical receivers, which can be prevented by irregular or fluctuating power levels. The price of commercial veriable optical attenuator depends on the production technology used ever.

FiberStore is a online shop supply Fiber Optic Attenuator FC, SC/APC, ST, PC, LC, UPC, MU, FC/APC, SC, LC/APC, fixed value plug type fiber optic attenuators with different attenuation level, from 1dB to 30dB.

The Difference Between Visual Fault Locator and Fiber Optical Identifier

Are one of the most important tools for testing in our network are Visual Fault Locator and Fiber Optical Identifier. But sometimes we mistake them as the same equipment. To tell the truth, they are different test tools.

1. Visual Fault Locator

Fiber visual fault locator is a kind of device which is able to locate the breakpoint, bending or cracking of the fiber glass. It can also locate the fault of OTDR dead zone and make fiber identification from one end to the other end. Designed with a FC,SC,ST universal adapter, this fiber fault locator is used without any other type of additional adapters, it can locates fault up to 10km in fiber cable, with compact in size, light in weight, red laser output.

This device is based on laser diode visible light source, when the light injected into the fiber, if fiber fracture, connector failure, bending over, poor weld quality failure by launching the light of the fiber to fiber fault visualization positioning.Visual Fault Locator launched a continuous wave (CW) or pulsed mode. The typical frequency of 1Hz or 2Hz, but can also work in the kHz range. Usually the output power of 0dBm (1mW) or less, the working distance of 2 to 5km, and to support all the common connector.

2. Fiber Optical Identifier

Fiber Optical Identifier, it is a very sensitive photodetectors. When you will be a fiber bending, some light radiation from the fiber core. The light will be detected by the fiber identification, technical staff according to these light can be a single fiber in the multi-core optical fiber or patch panel identified from the other fiber out.

Optical Fiber Identifier can detect the status and direction of the light does not affect the transmission. In order to make this work easier, usually at the sending end to the test signal modulated into 270Hz, 1000Hz or 2000Hz and injected into a specific fiber. Most of the optical fiber identifier for the operating wavelength of 1310nm or 1550nm single-mode fiber optical fiber, optical fiber identifier can use the macro bending technology to identify the direction and power of the transmission fiber and the fiber under test online.

Optical fiber identifier is an essential installation and maintenance instrument which can identify the optical fiber by detecting the optical signals transmitted through the cables, during this process the fiber optic identifier do no harm or damage to the fiber cable and it also do not need opening the fiber at the splice point for identification or interrupting the service.

The Optical Transceiver of XFP Transceiver

Having photonic and electrical layer normal accordance interfaces are small type component pluggable transceivers. Commercially marketed compact SFP modules are capable to support insofar as 4.25 Gbit/s and together with the previous types are enhanced SFP+ models that are aimed for greater data rates such as 8.5 Gbit/s and 10.52 Gbit/s Fiber Channel.

XFP Transceivers commercially available in the market now include the 10Gbase SR XFP, 10Gbase LR XFP, 10Gbase ER XFP and 10Gbase ZR XFP. These Fiber Transceivers are with Digital Diagnostics that provide a powerful optical management tool. 10Gbase SR XFP is used with OM3 50/125 laser optimized multimode fiber with max working span around 300 meters. The other three standards are all for single mode fiber applications, 10Gbase LR XFP work with 1310nm SMF and max working distance 10km, 10Gbase ER XFP work with 1550nm SMF and working range max 40km, 10Gbase LR XFP is also 1550nm wavelength and working span is 80km max.

The small size of one such interface permits it to take up a comparatively small amount of space along the edge of a network device motherboard, crucial for many transceivers to be hooked up at once. A lesser number of transceivers of the associated GBIC protocol can be joined to a compatible hub at a time, as the interfaces for that kind of transceiver are noticeably larger.

Fiber optic networks are simply an astounding technology. The elegance and efficacy of transferring a signal through lasers reflected off the sides of a microscopic tube are unparalleled. For any of this to operate properly, though, an optical transceiver is a requirement.

Communication being vital for every organization, the advent of technological development has led to a faster and improved mode of communication. The earlier communication devices were crude, which resulted in delayed and expensive processes of transmission.For the ones who are not very well aware of scalability, it would mean the potential or inherent capacity to rise beyond eight channels on one stand. This makes it easier to organize and manage a network.

What is Xenpak transceiver module? Xenpak transceiver module is one of the 10Gbps fiber optic transceiver modules. Xenpak transceiver is fully compatible with the IEEE 802.3ae standards for 10G Ethernet as required by Xenpak MSA. It is same at 121 x 36 x 18 mm (the biggest in 10G fiber transceiver modules); these modules typically weigh less than 300 g and with dual SC fiber interface.

The electronic, mechanical and optical features of these hot-plug devices are laid down by a multisource arrangement between network component dealers. SFP modules are inspired by GBIC interfaces only that they are designed with better port densities.

Fiber Optic Tools For Installers

The frequency of problems caused by fiber optic tool is high: their poor design, improper use, poor condition or the unfamiliarity with their use all are sources of problems during installation. Installation tools include some big hardware like bucket trucks, trenchers, cable pullers or plows. The need for these will be established early in the planning stages. Many contractors do not own expensive equipment like this, finding it more cost effective to rent it as needed. If your crews are not familiar with a particular piece of equipment, subbing the work to someone who has both the equipment and an experienced crew may be much more cost effective, as mistakes in their operation can be disastrous – both costly and dangerous.

Outside plant cables and premises singlemode cables will generally require fusion splicing for concatenation of long cable runs and splicing on pigtails for termination. Since fusion splicers have become less costly, more contractors have purchased them. Other contractors who have fewer projects that require splicing prefer to rent them, knowing they are getting a splicer that is a newer model with the latest technology that has been recently serviced. The downside of a rental unit is your installers may not be familiar with that model and require some training or time to familiarize themselves with it. If you own your splicer, it’s assumed your crews are familiar with its operation and need only to inspect the unit to ensure it’s working properly and the arc electrodes are in good condition.

Most contractors own termination equipment for multimode fiber as it is used on most jobs. Generally contractors have a preferred method of termination, either adhesive/polish or prepolished/splice types. Either type requires dedicated toolkits. For epoxy or Hot Melt terminations, the appropriate curing ovens will be required, and the two are quite different; the Hot Melt oven is much hotter and will ruin epoxy connectors if used on them by mistake. If you use epoxy or anaerobic adhesives from your stock, check the expiration dates on all of them to make sure they are fresh. Also check for other consumables like wipes, isopropyl alcohol, cable gel cleaner and of course, connectors.

Prepolished splice connectors have been getting better and easier to use. Newer termination kits include a quality cleaver like those used with fusion splicer and a visual fault locator to verify the internal splice. Since newer kits can now produce connectors that have lower losses, around 0.5 dB, a new kit (and perhaps some training) and the latest connectors could be a good investment.
When checking out the termination kits, pay particular attention to the condition of the tools. Of course missing tools will need replacement, but hopefully that was done when the kits were inspected after the last job. However, jacket strippers, fiber strippers and cleavers can wear out or be damaged, so its important to check their operation with some sample fibers to see if they are working properly.

Let me repeat that thought: It’s mandatory to check out every piece of equipment you intend to take to a job site to ensure its proper operation and let the installation crew reacquaint themselves with its operation. This process needs to be done with enough time to have the unit serviced or replaced and restock any consumable supplies. It should also be obvious that one never puts back on the shelf any equipment that has had problems in the field. It should immediately be replaced or sent out for repair to be ready for the next job or discarded.
Let me caution you on another problem we have seen recently with tools. Several recent complaints of poor quality tools, especially fiber strippers, have led us to believe that poor quality imports are becoming more common. In one case, the tools appear to have been counterfeit, branded with a well-known American name. I suggest you purchase tools only from reputable sources and inspect them on receipt to ensure they work properly.
Finally, as the equipment is checked out and readied for use, make certain that appropriate safety equipment is packed with the tools. Everyone who works with fiber needs safety glasses and clean, unscratched ones will make seeing those hair-thin fibers much easier. Black work mats for splicing and termination also help the installer see the fibers and find fiber scraps for easier cleanup.

Integrated Cabling Network Connection Between The Optical Fiber Equipment

Since the optical fiber and fiber optic port prices are still very expensive, so the optical fiber is mainly used for optical fiber is mainly used for the connection between the core switch and the aggregation layer switches, or used in the aggregation layer switches between the cascade. Should be noted that the fiber ports do not have the ability to stack can only be used in cascade.

1. Fiber optic jumper wire cross connection

In all switches are two fiber ports that pitch-catch. Of course, fiber jumpers must be 2, otherwise wouldn’t be able to communicate between the ports. When the switch via fiber optic port cascade must be at both ends of the fiber jumpers transceiver swap, when the a Termination “receive” the other end “send.” Similarly, when one end of the “send” elbow, the other end to close. “ Cisco GBIC fiber module marked transceiver flag, left side inward arrows indicate the “revenue”, the right side of the outward arrows indicate the “send”, the port LED is not lit, the connection failed. Only when the fiber port after the success of the LED light into green.

Similary, when the convergence layer switch is connected to the core switches, between the transceiver ports of the optical fiber must also be cross-connections, as shown:

2. The connection of the optoelectronic transceiver

When the fiber optic cable integrated wiring between buildings or between floors while the horizontal cabling using twisted pair connection between the two transmission media. First, using the same time has a fiber port and RJ-45 port switch, switch between the interconnection between the photoelectric port; using inexpensive photoelectric conversion device, connect one end of the optical fiber, the other end connected to the switch twisted pair ports photoelectric conversion between, as shown:

Comparatively speaking, the higher transmission performance modular switches, photoelectric conversion devices cheaper. Therefore, it should be based on the network data transmission needs determined and the amount of investment which equipment. It needs to be noted that not all fiber transceivers to support full-duplex, some products only support half-duplex, and should therefore pay attention to identify at the time of purchase. In addition, taking into account the compatibility suggested the use of the products of the same brand and type.

One end of the optical transceiver connected to the fiber optic patch panels using fiber optic jumper with the remote fiber-optic interface connection; using twisted pair jumper the other end connected to the RJ-45 port switch, with the other computers on the switch connection to complete the network backbone fiber optic transmission.
